摘要
不同温湿组合对甜菜夜蛾各虫态生长发育和繁殖力有明显的影响,适宜该虫生长发育的温湿度为26℃与RH80%或RH94%两个组合.在这种条件下,其卵孵化率、1~5龄幼虫存活率、蛹羽化率、雌虫比率、产卵的雌虫比率和平均产卵量分别为82.63%~83.70%、81.90%~82.47%、88.00%~88.03%、90.40%~91.00%、93.36%~94.17%、95.97%~96.26%、92.77%~94.16%、0.42~0.43、0.98和605~606粒/雌,且明显高于其它温湿组合.在温湿度为32℃与RH94%条件下,该虫的内禀增长能力最大(0.225).
Different combinations of temperature and relative humidity(RH) significantly affected
the development and the fecundity of beet armyworm ( Spodoptera exigua ). The combination
of 26℃ and RH 80% or 94% was optimal for the development of beet armyworm. Under this
combination, the hatchability of egg, the survival rate of 1~5 instar larvae, the rates of
emergence, female, and female ovipositing, and the mean quantity of oviposition were 82.63~
83.70%, 81.90 ~82.47%,88.00~88.03%, 90.40~91.00%, 93.36~94.17%, 95.97~96.26%,
92.77~94.16%, 0.42 ~0.43, 0.98 and 605~606 eggs/female respectively, which were all
significantly higher than those of other combinations. Under combination of 32℃ and RH 94%,
the population's innate capacity of increase was the highest ( 0.225 ).
